provides functions to remove accents using UTF16 as a pivot

Text::Unaccent is a module that provides functions to remove accents
from a string. For instance the string été will become ete. The
charset of the input string is specified as an argument. The input is
converted to UTF-16 using iconv(3), accents are stripped and the
result is converted back to the original charset. The iconv -l
command on GNU/Linux will show all charset supported.
